Is there a way to tell Tapestry to use:
validate="${validationText}"so if getValidationText returns the string "required" it will act the same way as if you wrote: validate="required"? -----Original Message----- From: jackkuros...@w9z.org Sent: Tuesday, May 24, 2011 2:47pm To: "Tapestry users" <users@tapestry.apache.org> Subject: Re: dynamic validation for required / not required Thats helpful, but my problem is that I don't know the field id either, so I can't inject the field. The fields are determined at run time (attributes that the user can add or remove) so it has to be flexible. I supposed I could put every TextField in an IF statement where the IF has "required" and the ELSE doesn't, but that seems like I'm missing a better way to do it.

Then create a FieldValidator getValidator() method using createValidators() and add t:validate="prop:validator" to your TextField. Example (taken from http://tapestry.1045711.n5.nabble.com/Validation-based-on-condition-td2435565.html): @Inject private FieldValidatorSource source; @InjectComponent private Field yourField; public FieldValidator getDynamicConstraints() { return source.createValidators(yourField, "required", null); } --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
